Step-induced defects in thin films and the effect on their electrical and magnetic properties
(Trinity College (Dublin, Ireland). School of Physics, 2015)
This thesis investigates step-induced defects in thin films and their effect
on the electrical and magnetic properties. Stepped epitaxial Fe3O4 thin films with
different thickness were fabricated and their magnetic properties ...
Graphene Based Membranes for Osmosis Applications
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)
With the discovery of two-dimensional hexagonal graphene (single layer of graphite), a tremendous interest has grown due its remarkable properties. Apart from all other properties, its superior thickness (one-atom thick) ...
The Growth and Characterisation of Mn2Au Thin Films and Heterostructures
(Trinity College Dublin. School of Physics. Discipline of Physics, 2023)
In this thesis, Mn2Au thin films and heterostructures are grown via molecular beam
epitaxy. Mn2Au thin films are investigated on MgO (001) and Al2O3 (1102) substrates,
and on Pt (111) seed layer grown on an Al2O3 (0001) ...
Logarithmic growth of local entropy and total correlations in many-body localized dynamics
(2020)
The characterizing feature of a many-body localized phase is the existence of an extensive set of quasi-local conserved quantities with an exponentially localized support. This structure endows the system with the signature ...
Fabrication and characterisation of chemical vapour deposition grown branched carbon nanotube arrays
(Trinity College (Dublin, Ireland). School of Physics, 2007)
The fabrication, optimisation and characterisation of arrays of straight and junction
multiwall carbon nanotubes (MWNTs) is presented in this thesis. A detailed description of
the design and fabrication of the chemical ...
Two-photon absorption based detection in semiconductor microcavities
(Trinity College (Dublin, Ireland). School of Physics, 2009)
The most important feature of a two-photon absorption microcavity (TPAM) is
that of its enhancement of the optical field which enhances the level of twophoton
absorption (TPA) for a particular input optical power incident ...
Photophysics of a poly(phenylenevinylene) with alternating meta-phenylene and para-phenylene rings

Fabrication of magnetic force microscopy tips by electrodeposition and focused ion beam milling
(IEEE, 2008)
A method is described for the fabrication of magnetic force microscopy tips via localized electrodeposition and focused ion beam
milling departing from commercial tapping mode tips. Very high aspect ratios and interacting ...
Solution processed Group V1 transition metal dichalcogenides : a study on conductive hybrids and photoconductivity for future applications in printed electronics
(Trinity College (Dublin, Ireland). School of Physics, 2014)
Transition metal dichalcogenides (TMDs) constitute a class of inorganic layered compound
with generalised MX2 stoichiometry, where M denotes a transition metal atom
and X a chalcogen atom of sulfur, selenium or tellurium ...
Vortex state in ferromagnetic nanoparticles
(2014)
The evolution of the magnetic state of a soft ferromagnetic nanoparticle with its size is usually thought to be from superparamagnetic single domain to blocked single domain to a blocked multidomain structure. Néel pointed ...
